    摘要: A toner includes a binder resin including a copolymer resin (A) having a structural unit derived from a crystalline polyester resin (A1) and another structural unit derived from an amorphous polyester resin (A2), and an amorphous resin (B) in an amount of from 30 to 70% by weight based on total weight of the binder resin. The binarized image of the AFM phase image of the binder resin consists of first phase-contrast images serving as large-phase-difference portions and second phase-contrast images serving as small-phase-difference portions with the first phase-contrast images dispersed in the second phase-contrast images forming a dot-like or streaky structure. The average value of dispersion diameters, corresponding to maximum Feret diameters, of the first phase-contrast images in the dot-like structure, or widths, corresponding to minimum Feret diameters, of the first phase-contrast images in the streaky structure, is less than 100 nm.

    摘要: A toner is provided. The toner includes a crosslinked polyester resin, and a block copolymer. The crosslinked polyester resin includes a diol component, which includes an aliphatic diol component having 3 to 10 carbon atoms in an amount of 50% by mole, and a crosslinked component, which is at least one of a crosslinked component of an aliphatic alcohol having three or more valences and a crosslinked component of an aliphatic acid having three or more valences, and the block copolymer includes a crystalline segment (a) and a non-crystalline segment (b). The toner has a first glass transition temperature (Tg1st) of from 20° C. to 50° C., which is determined by subjecting the toner to differential scanning calorimetry (DSC) and measuring a glass transition temperature in a first temperature rising process in the differential scanning calorimetry (DSC).
